Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The service degradation method provided by the present invention can be applied to the communication system shown in fig. 1. As shown in fig. 1, the communication system includes a service detector, a service gateway, a service end, a storage unit, a user, and may further include a configuration unit and a database, where the connection relationship is as shown in fig. 1, it should be noted that a plurality of service ends may be provided, and respectively provide different services, each service may correspond to at least one storage unit, and only one service end and one storage unit are shown in fig. 1. The storage unit may be a CDN (Content Delivery Network), and the CDN has a basic principle that various cache servers are widely used, and are distributed to a region or a Network where user access is relatively concentrated, and when a user accesses a website, the access of the user is directed to a cache server that is closest to the user and works normally, and the cache server directly responds to a user request; the service detector can send a request to a server through the service gateway at preset time intervals to acquire service data, monitor whether the service is available according to the request state and the returned service data, inform the service gateway to start service degradation if the service is unavailable, and push the latest service data to a storage unit corresponding to the service through the service gateway if the service is determined to be available after the service detector requests the service data each time; after receiving a service request of a user, if the service is identified to be degraded, the service gateway directly acquires service data from a storage unit corresponding to the service and returns the service data to the user, and if the service is not degraded, the service gateway directly acquires the service data from the service end. The service degradation process is described in detail below with reference to specific embodiments.
Fig. 2 is a flowchart of a service downgrading method according to an embodiment of the present invention. The embodiment provides a service degradation method, wherein an execution subject is a service detector, and the method comprises the following specific steps:
s101, service data is requested to a server through a service gateway. .
In this embodiment, the service probe sends a service request to the server through the service gateway at preset intervals, and receives the returned service data. Further, the service detector may request service data from the service end through the service gateway according to a preset polling interval time, so that the service data in the storage unit corresponding to the service may be updated. It should be noted that, no matter whether the service is degraded or not, the service detector may access the service end to obtain the service data, so as to determine whether the service can be recovered or not after the service is degraded. In addition, if there are multiple services, the service probe may send requests to each server in turn.
S102, monitoring whether the service of the server is available.
In this embodiment, the service detector monitors whether the service is available, specifically, a return code of the interface may be received each time the service detector requests the service, where the return code is preset, for example, 0 is returned when the service is available, and-1 is returned when the service is unavailable (for example, the service is busy), and the service detector may determine whether the service is available by identifying the return code. In addition, a data range may also be preset, and after the service detector acquires the service data each time, the service data is analyzed, and if the analysis result exceeds the data range, the service is determined to be unavailable, for example, a commodity price range is preset, and when the commodity price in the analyzed service data exceeds the commodity price range, the service data is indicated as an error, and further, the service is indicated as unavailable. Since the service detector may send the service request periodically, the determination of whether the service is available in this embodiment may be performed periodically accordingly. Of course, whether the monitoring service is available or not in this embodiment is not limited to the above example, and other monitoring methods may be adopted, which are not described herein again. If the service detector does not monitor whether the service is available or not by requesting service data from the server, the sequence of S101 and S102 is not limited.
S103, if the service is available, pushing the service data to a storage unit corresponding to the service.
In this embodiment, the service detector pushes the service data to the storage unit corresponding to the service through the service gateway after confirming that the service is available, so as to periodically update the service data in the storage unit, but in this embodiment, the service detector or the service gateway may also control the service to directly push the service data to the storage unit corresponding to the service. When the service detector determines that the service is unavailable, the service data in the storage unit may not be updated, so as to avoid uploading erroneous service data to the storage unit (for example, service data beyond a preset data range). The storage unit may be a content delivery network CDN.
And S104, if the service is unavailable, informing the service gateway to start a service degradation mode for the service so that a user requests service data from a storage unit corresponding to the service through the service gateway.
In this embodiment, when the service detector determines that the service is unavailable, the service gateway is notified to start a service degradation mode for the service, and then if a service request is received by a user, service data is obtained from a storage unit corresponding to the service. In the system, there may be more than one service, the service degradation is only for the unavailable service, and the user acquires the service data from the storage unit corresponding to the unavailable service.
In the service degradation method provided by this embodiment, a service detector requests service data from a service end through a service gateway, and monitors whether the service is available, and if the service is available, pushes the service data to a storage unit corresponding to the service; and if the service is unavailable, the service detector informs the service gateway to start a service degradation mode for the service, and the user requests service data from the storage unit corresponding to the service through the service gateway. Because the service data in the storage unit is updated by the service detector when the service is available, the service data acquired from the storage unit by a user after the service degradation is basically consistent with the real data, the elegant degradation of the reading service with no particularly high requirement on the data consistency is realized, and the service and the user experience are not influenced.
On the basis of the foregoing embodiment, if the service is unavailable in S103, the service detector notifies the service gateway to start a service degradation mode for the service, which may specifically include:
and if the service is unavailable, the service detector sends a first service state identifier modification instruction to the service gateway, so that the service gateway configures the service state identifier of the service as unavailable according to the first service state identifier modification instruction.
Further, if the service is available, the service detector sends a second service state identifier modification instruction to the service gateway, so that the service gateway configures the service state identifier of the service to be available according to the second service state identifier modification instruction.
In this embodiment, when it is determined that a certain service is not available, the service detector controls the service gateway to modify the service state identifier of the service into unavailable, when a user requests the service, the service gateway first identifies the service state identifier of the service, if the service state identifier is available, the service gateway obtains service data from the service according to the service request and returns the service data to the user, and if the service state identifier is unavailable, the service gateway obtains the service data from a storage unit corresponding to the service according to the service request and returns the service data to the user. The embodiment configures the service state identifier at the service gateway, thereby implementing the start and shutdown of service degradation.
In the foregoing embodiment, the step S102 of monitoring, by the service detector, whether the service is available may specifically include:
the service detector receives a return code sent by the service gateway after requesting service through the service gateway, compares the return code with a preset return code, and determines that the service is unavailable if the return code is matched with a service abnormal return code in the preset return code; and/or
And the service detector analyzes the returned service data, judges whether an analysis result meets a preset data range, and determines that the service is unavailable if the analysis result does not meet the preset data range.
In this embodiment, whether the service is available or not may be determined by the return code and/or the service data parsing result, where a preset return code is agreed in advance, for example, 0 is returned when the service is available, and-1 is returned when the service is abnormal (for example, the service is busy), the return code of the interface is received each time the service probe requests the service, and the service probe may determine whether the service is available or not by identifying the return code. And a preset data range can be predetermined, the service detector analyzes the service data each time after acquiring the service data, and if the analysis result exceeds the data range, the service is judged to be unavailable.
Further, whether the service is available or not can be judged by using the return code, if the return code is matched with the service abnormal return code, the service data is not analyzed, and the unavailability of the service is directly determined; and when the return code is not matched with the service abnormal return code, further analyzing the service data, judging whether the analysis result meets a preset data range, if not, determining that the service is unavailable, and if so, determining that the service is available.
On the basis of the above embodiment, the method may further include:
and the service detector receives a service degradation strategy sent by a configuration unit, wherein the service degradation strategy comprises the preset interval time and/or the preset return code and/or the preset data range.
In this embodiment, a development engineer or a manager may configure the service degradation policy in a personalized manner, for example, set or modify a preset interval time and/or a preset return code and/or a preset data range in the configuration unit according to a requirement, and after the configuration unit configures the service degradation policy, the service degradation policy is sent to the service detector, so as to perform service degradation according to the service degradation policy. In addition, a development engineer or a manager can also force service degradation, a forced service degradation instruction is sent to the service detector through the configuration unit, and the service detector informs the service gateway to start a service degradation mode for the service according to the forced service degradation instruction.
According to the service degradation method provided by the embodiment, the service detector updates the service data in the storage unit corresponding to the service when the service is available, so that the service data acquired from the storage unit by a user after the service degradation is basically consistent with the real data, the elegant degradation of the reading service without particularly high requirement on data consistency is realized, and the service and the user experience are not influenced. In addition, automatic opening or closing of service degradation can be realized, and manual operation is not needed; meanwhile, the method does not need to be coupled with the service, and has better flexibility and expandability.
Fig. 3 is a flowchart of a service downgrading method according to an embodiment of the present invention. The embodiment provides a service degradation method, wherein an execution subject is a service gateway, and the method comprises the following specific steps:
s201, receiving a service request, and identifying a source of the service request.
In this embodiment, since the service probe can access the service acquisition service data regardless of whether the service is degraded or not, and the user can only acquire the service data from the storage unit after the service is degraded, the service gateway needs to identify whether the source of the service request is the service probe or the user. The storage unit may be a content delivery network CDN.
S202, if the service request is sent by a service detector according to a preset polling interval time, the service gateway obtains service data from a service end according to the service request and returns the service data to the service detector, and after receiving a push instruction sent by the service detector when the service detector determines that the service of the service end is available, the service data is pushed to a storage unit on the CDN corresponding to the service by the service detector through the service gateway.
In this embodiment, the service probe sends a service request to the server through the service gateway, receives the returned service data, and when the service probe determines that the service of the server is available, pushes the service data to the storage unit corresponding to the service through the service gateway, so as to update the service data in the storage unit. Of course, the service data can also be pushed directly to the corresponding storage unit by the service detector or the service gateway control service. The service detector can request service data from the server through the service gateway at preset intervals, so that the service data in the storage unit can be periodically updated. When the service detector determines that the service is unavailable, the service detector may not send a push instruction to the service gateway to update the service data in the storage unit, so as to avoid uploading wrong service data to the storage unit (for example, service data beyond a preset data range).
S203, if the service request is sent by the user, requesting service data to the service or the storage unit corresponding to the service according to whether the service starts a service degradation mode and returning the service data to the user.
In this embodiment, when a user sends a service request, if the service degradation mode is not started at this time, service data is requested from the service and returned to the user, and if the service degradation mode is started at this time, service data is requested from a storage unit corresponding to the service and returned to the user.
In this embodiment, S202 and S203 do not have any sequence, and no conflict occurs, for example, when the service gateway receives service requests sent by the service detector and the user at the same time, S202 and S203 are respectively executed.
In the service degradation method provided by this embodiment, a service detector requests service data from a service end through a service gateway, and monitors whether the service is available, and if the service is available, pushes the service data to a storage unit corresponding to the service; and if the service is unavailable, the service detector informs the service gateway to start a service degradation mode for the service, and the user requests service data from the storage unit corresponding to the service through the service gateway. Because the service data in the storage unit is updated by the service detector when the service is available, the service data acquired from the storage unit by a user after the service degradation is basically consistent with the real data, the elegant degradation of the reading service with no particularly high requirement on the data consistency is realized, and the service and the user experience are not influenced.
On the basis of the above embodiment, the method may further include:
when the service gateway receives a first service state identifier modification instruction sent by the service detector after judging that the service is unavailable, configuring the service state identifier of the service as unavailable according to the first service state identifier modification instruction;
and when the service gateway receives a second service state identifier modification instruction sent by the service detector after judging that the service is available, configuring the service state identifier of the service to be available according to the second service state identifier modification instruction.
In this embodiment, when the service detector determines that a certain service is unavailable, the service detector controls the service gateway to modify the service state identifier of the service into unavailable, when the user requests the service, the service gateway first identifies the service state identifier of the service, if the service state identifier is available, the service gateway obtains service data from the service according to the service request and returns the service data to the user, and if the service state identifier is unavailable, the service gateway obtains the service data from the storage unit corresponding to the service according to the service request and returns the service data to the user. The embodiment configures the service state identifier at the service gateway, thereby implementing the start and shutdown of service degradation.
That is, in S203, the service gateway requests the service or the storage unit corresponding to the service for service data to be returned to the user according to whether the service opens the service degradation mode, specifically including:
the service gateway identifies the service state identification of the service;
if the service state identification is available, the service gateway acquires service data from the service end according to the service request and returns the service data to the user;
and if the service state identifier is unavailable, the service gateway acquires service data from a storage unit corresponding to the service according to the service request and returns the service data to the user.
According to the service degradation method provided by the embodiment, the service detector updates the service data in the storage unit corresponding to the service when the service is available, so that the service data acquired from the storage unit by a user after the service degradation is basically consistent with the real data, the elegant degradation of the reading service without particularly high requirement on data consistency is realized, and the service and the user experience are not influenced. In addition, automatic opening or closing of service degradation can be realized, and manual operation is not needed; meanwhile, the method does not need to be coupled with the service, and has better flexibility and expandability.

s301, the service detector requests service data from the service end through the service gateway according to the preset interval time.
S302, after the service detector requests service through the service gateway, receiving a return code sent by the service gateway, comparing the return code with a preset return code, and if the return code is matched with a service abnormal return code in the preset return code, judging whether the service is available; and/or the service detector analyzes the returned service data and judges whether the analysis result meets a preset data range, thereby judging whether the service is available.
